Difference between import and static import. The import allows the Java programmer to access classes of a package without package qualification whereas the static import feature allows accessing the static members of a class without the class qualification..
Also to know is, what is the static import in Java?
Static import is a feature introduced in the Java programming language that allows members (fields and methods) which have been scoped within their container class as public static , to be used in Java code without specifying the class in which the field has been defined.
Likewise, is static import bad? If you overuse the static import feature, it can make your program unreadable and unmaintainable, polluting its namespace with all the static members you import. Importing all of the static members from a class can be particularly harmful to readability; if you need only one or two members, import them individually.
One may also ask, what is the meaning of import in Java?
